HOPPER-DUMP-CAR CONSTRUCTION.

Specification of LettersI Patent.

Patented Apr. 15,1919.

To all 'whom t may con-cern Be it known that L'HARRY S. HART, a citizenof Athe United States, residing at Chicago, in the 'county of Cook andState of Illinois, have invented certain'new and useful' Improvements inHopper-Dump-Car Constructions, of which the following is aspecification.

This invention relates tp dump cars.

The object of this invention is to simplify and improve dump. carconstructions in a novel manner to increase the capacity thereof and atthe same time retain the self-cleaning feature.

' tion;

This and other objects are accomplished by means of the arrangementdisclosed by the accompanying sheets of drawings, in which- Y 4 Figure 1is a fragmentary side elevation of a railway dump car embodying myinven- .F ig. 2 is a fragmentary plan View of the same car;

I endo i verse center line of the car, itis found that and,

trucks.

Fig. 3 is a transverse sectional view of the same dump car taken overone of the trucks;

Fig. 4 isa transverse sectional view ofthe same ear taken between thetrucks.

It isa well recognized fact that it is of vital importance to increasethe carrying capacity of railway cars, and especially,

the capacity can be effectively increased by changing the floorconstruction over the Referring to the figures of the drawings, it willbe noted that Ihave shown a dump car including sides 10, ends 1l and afloor, the floor portions over the trucks being of A-shaped constructionin which the apex l2 of the A is located over the center sill 13, the

sloping members 14 of the A-shaped portion extending downwardly andoutwardly to- Award the sides vot' the car. These sloping floor members14: preferably are stationary and connected to the under frame tothereby increase the stiffness and rigidity-of the car structure. Thedischarge openings at the lower ends of the floor portions lit normallyare closed by side dump doors 15 which preferably are pivotallyconnected at 16 along the lower edges of the sides lO of the car, theswinging edges of the doors 15 when in closed position forming a tightseal Withithe lower edges of the floor members 14. The dump doors 15 maybe provided with any suitable operating mechanism including operatingshafts 17,-preferably carried by the doors 15 and also chains 18, which'connect the shafts with the stationary floor portions 14. s

The floor intermediate the trucks is at a lower level thanthe ioorportions over the trucks and includes a plurality of transverselyarranged hoppers 19 formed by transversely extending shedding members20, there being transversely arranged hoppers 19 on both sides of thelongitudinal center of the car, the longitudinal division of the carbeing formed. by shedding means 21. Each of the transversely arrangedhoppers 19 hasits ioor portion composed 1n part by a plurality of doors22 hinged transversely of the car and swinging toward and from eachother to. closed and opened positions, respectively. Leading from theextreme doors 22 nearest the ends of the car are sloping ioor members 23which extend to the apex 12 of the loor portions over the trucks. Incars heretofore built the sloping floor portion ,23 is continued in thesame plane to the end 11 of the car. It is apparent, therefore, thatbyproviding the floor construction over the trucks, as shown -in thisapplication, the carrying capacity of the dump car is greatly increasedand at the same time the selfcleaning teature is re tained. When theside dump doors 15 are opened, it will be appreciated that all of thedumpable material over'the trucks will be discharged to either side ofthe car, and when the transversely arranged dump doo-rs 22 are opened,the remainin dumpable material in the car will be discarged intermediatethe trucks, all of the ioor portions being slanting or movable in amanner .such that the car will completely discharge its load uponopening of the doors. The transversely arranged dump doors may be pro- Ivided with any nism 24 from each other to closed and' openedpositions,respectively.
